BELT-REPLACER.

SPECIFICATION forming part of Letters Patent No. 368,094, dated August 9, 1 887.

Application filed May 1'7, 1887. ScrialNo. 238,511. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. KNIGHT, a citizen of the United States, and a resident of Colfax, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Belt-Replacers; and I do hereby declare thatthefollowi ngisa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figurel is a side view of a pulley, showing my improved belt-replacer in operation securing the belt to the periphery of the pulley. Fig.2. is a similar view showing the belt in place and the replacer in the act of being liberated from the pulley and belt. Fig. 3 is a perspective view of the replacer, showing it locked. Fig. 4 is a face view of the same, showing it unlocked; and Fig. 5 is asectional view on line as as, Fig. 3.

Similar numerals of reference indicate corresponding parts in all the figures.

My invention relates to that class of devices for placing belts on pulleys in which the belt is clamped to the rim of the pulley by means of a clamp which will be released by the straightening of the belt when the latter is carried entirely around the pulley and .is- ,securely in its place; and it consists in the improved construdtion and combination of partsof such a device, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates a bar which is formed with a groove or way in its upper face, formed by means of inwardly-bent flanges 2 at the side edges. Rigidly secured between these flanges at one end of the bar is another bar, 3, one end of which, 4, is bent at a right angle, or nearly so, to form a lip. A bar, 5, having one end bent to form a lip, 6, slides with itsstraight portion in the way or groove of the first bar. The rigid bar 3 is provided with a post, 7, projecting from one edge,while thesliding bar is provided with a similar post, 8, projecting from the opposite edge.

A bar, 9, is pivoted near one-end to the in ner face of the post 7, audits long arm is formed with a series of perforations, 10, in which the inner end of a curved arm, 11, is secured upon a screw or bolt, 12, the outer end of the putwardly-bulged arm being provided with a curved transverse bearing-strip, 13, upon its under side.

One end of a bar, 14, is pivoted to the end of the short arm of the pivoted bar 9, and the greater portion of this bar is formed with a longitudinal slot, 15, and with a serrated outer face, 16, the serrations of the face having, preferably, the steep sides facing toward the pivoted end and standing transverse to the bar.

A nutted bolt, 17, is inserted through the slot of the bar 14 and through the upright or post 8 upon the sliding bar, and a washer, 18, having its inner face, 19, serrated to correspond, to the serrations of the slotted bar, is placed upon thebolt between the upright and the slotted bar, havingits serrations engaging the serrations of the bar, a spring-plate, 20, upon the post preventing the nut 17 from turning.

hen the device is to be used in placing a belt upon a pulley, the bolt securing the slotted bar is loosened, so as to allow the sliding bar to be drawn out suificiently to bring the lips .of both bars to bear against the edges of the rim of the pulley and to clamp it firmly when the two pivoted bars are tilted parallel to each other, as in Fig. 3, the slotted bar being secured and adjusted at that point by means of the nutted bolt and the serrated washer. The belt is then placed upon the face of the pulley and tightly secured in place by drawing the lips of the two bars against the edges of the pulley. These lips are moved to ward each other to clamp them against the edges of the pulley by moving the end of the curved bar inward toward the face of the pulley, it having been first moved or tilted outward, as shown in Fig. 4, to'open the lips sufficiently to freely pass over the edges of the pulley. As now the pulley is revolved, the clamping device will carry the belt around upon the rim of the pulley, bringing it in place, and when the belt is entirely in place the portion of the belt being straightened will tilt the curved arm of the device outward, the said arm projectingin the direction of the revolution, and this arm being tilted outward will tilt the pivoted bar outward, sliding the slotted bar and the sliding bar to one side, re-

ICO

leasing it from the rim of the pulley and allowing the device to drop oil, the device thus pntting the belt in place and doing away with all necessity of bringing the hands in contact with the belt or pulley alter the pulley is started, and thus avoiding the danger of any accident happening to the person placing the belt upon the pulley.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States-- i 1. In a device for placing belts upon pulleys, the combination of a grooved bar having an iuwardly-projecting lip upon one end and having a post near that end with a bar sliding in the grooved bar and having its end bent into a lip and having a post upon its outer side, an arm adjustably pivoted to the post of the sliding bar, and a bar pivotally connected at one end to the pivoted arm and pivoted upon the post of the grooved bar and having a curved arm projecting from its free end in the direction of the revolutionof the belt, as and for the purpose shown and set forth.

2. In a device for placing belts upon pulleys, the combination of a bar having one end bent into a lip and having a groove or way formed upon its outer side by bent side flanges with a bar sliding in the 'groove or way and h.av--

ing a lip at its outer end, a longitudinallyslotted bar having a serrated outer face, a bolt inserted through the slot and into a post upon the sliding bar and having a nut upon its outer side secured from turning by a spring-plate upon the post, a serrated washer upon the bolt between the slotted bar and the post, a bar pivoted near one end upon a post near the end of the grooved bar and having its short arm pivoted to the end of the slotted bar and having a series of perforations in its long arm, and a curved arm secured with a bolt in its inner end in one of the perforations and having an outward bulge and having a curved transverse bar upon its outer end, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

XVILLIAM B, KNIGHT.
